Let's divide 645356 by 20
We want to divide 645356 by 20.

Advancing to step 1:
6 divided by 20 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 20

Moving on to step 2:
When dividing 64 by 20, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 60 from 64 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 20

Going ahead to step 3:
20 goes into 45 2 times with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 40 from 45, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 20

Let's proceed to step 4:
When dividing 53 by 20, we get 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 322.0
Subtracting 40 from 53 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 20

Let's proceed to step 5:
If we divide 135 by 20, we get 6 and a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 3226.0
Subtract 120 from 135 to get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 20

Going ahead to step 6:
If we divide 156 by 20, we get 7 and a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 32267.0
Subtract 140 from 156 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
160 divided by 20 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 32267.8
Subtracting 160 from 160 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 32267.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32267.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 32267.8 with a balance of 0.0.
